Physical Aging in a Colloidal Glass Subjected to Concentration
Submitted for the MAR15 Meeting of The American Physical Society Physical Aging in a Colloidal Glass Subjected to Concentration Jump Conditions1 XIAOGUANG PENG, GREGORY B. MCKENNA, Department of Chemical Engineering, Texas Tech University, Lubbock, 79409, Texas, USA — We have prepared a thermo-sensitive core-shell PS-PNIPAM/AA latex system and have investigated the aging dynamics of its colloid...
متن کاملAging in a Structural Glass
We discuss the relaxation dynamics of a simple structural glass which has been quenched below its glass transition temperature. We demonstrate that time correlation functions show strong aging effects and investigate in what way the fluctuation dissipation theorem is violated. PACS numbers: 61.20.Lc, 61.20.Ja, 02.70.Ns, 64.70.Pf Typeset using REVTEX Talk given at STATPHYS 20, Paris, July 20-24 ...
متن کاملAging in a Topological Spin Glass
Using a combination of static and time dependent magnetic susceptibility measurements we have examined the nonconventional spin glass phase of the 2-dimensional kagomé antiferromagnet (H3O)Fe3(SO4)2(OH)6. In contrast with 2-dimensional site-disordered spin glasses, ac susceptibility results show critical behaviour at finite temperatures. This transition agrees well with a predicted anisotropy-d...
متن کاملEvolution of collective motion in a model glass-forming liquid during physical aging.
At temperatures moderately below their glass transition temperature, the properties of many glass-forming materials can evolve slowly with time in a process known as physical aging whereby the thermodynamic, mechanical, and dynamic properties all drift towards their equilibrium values. In this work, we study the evolution of the thermodynamic and dynamic properties during physical aging for a m...
متن کاملPhysical aging and relaxation of residual stresses in a colloidal glass following flow cessation
Dilute Laponite suspensions in water at low salt concentration form repulsive colloidal glasses which display physical aging. This phenomenon is still not completely understood and in particular, little is known about the connection between the flow history, as a determinant of the initial state of the system, and the subsequent aging dynamics. Using a stress controlled rheometer, we perform st...
